At Margaret O'Keefe's farm in East Texas, they grow high-quality Bermuda grass. The fields are flat and vibrant green, surrounded by woods of a darker, richer green. The family loves this land. O'Keefe inherited it from her mother, who divided it among eight children.

"She used to call it 'enchanted valley,' " O'Keefe says.

But her "enchanted valley" also lies in the path of the Crosstex NGL Pipeline.
